Every 100 kcal of soy flour (full-fat) brings 8.7 g of protein. On that measure it ranks 19th of the 31 soy foods in this database and 279th of all 796 foods on the site. Measured by weight instead, its 37.8 g per 100 g ranks 5th in its group.
Protein accounts for roughly 35% of the calories in soy flour (full-fat), making it very protein-dense. The rest comes from fat and carbohydrate, so it adds a solid amount of protein while still carrying real energy - useful when you are eating to a calorie target rather than under one.
Weight for weight, soy flour (full-fat) has 1.8 g of protein for each gram of fat (37.8 g against 20.6 g per 100 g).
Set against meatless deli slices, another soy food entry in the database, a serving carries about 2.9 g more protein (meatless deli slices has 5 g per 1 slice).
It is a complete protein - it supplies all nine essential amino acids in adequate amounts, so it can carry a meal's protein on its own. The serving quoted here is measured by volume at 21 g, and it covers about 16% of the 50 g FDA Daily Value for protein.
